Which solution will satisfy these requirements?
Configure Amazon EFS Amazon Elastic File System (Amazon EFS) storage and set the Active Directory domain for authentication.
Create an SMB file share on an AWS Storage Gateway file gateway in two Availability Zones.
Create an Amazon S3 bucket and configure Microsoft Windows Server to mount it as a volume.
Create an Amazon FSx for Windows File Server file system on AWS and set the Active Directory domain for authentication.
Explanations:
Amazon EFS does not natively support SMB (Server Message Block) protocol, which is required for Windows file shares. While it can integrate with Active Directory, it is primarily designed for Linux-based workloads and not optimized for Windows environments.
An AWS Storage Gateway file gateway can provide SMB file shares, but it does not directly integrate with Active Directory for authentication in a highly available manner. The setup may not provide the level of availability that a fully managed solution like Amazon FSx offers.
Amazon S3 is an object storage service and does not support SMB natively. Mounting an S3 bucket as a volume in Windows is not straightforward and would require additional configurations (like using S3FS or similar tools), which complicates the integration with Active Directory and availability needs.
Amazon FSx for Windows File Server provides fully managed native SMB file shares and integrates seamlessly with Active Directory for authentication. It is designed for Windows workloads, ensuring high availability and redundancy across multiple Availability Zones.
To the best of my knowledge, the answer is:
Create an Amazon FSx for Windows File Server file system on AWS and set the Active Directory domain for authentication.
